To all whom it may concern.'

Be it known that I, WILLIAM; I-Liwirnn, a

subject of the King of England, residing at Edmonton, in the Province of Alberta and Dominion of Canada, have invented certain new and useful Improvements in Smokestacks, of which the following is a specilication.

This invention relates to smokejacks or stacks for conveying the smoke. from a locomotive when placed in position in a round house'or shed to the outer atmosphere, vand is designed as an improvement of the jack shown in Patent Number 1,322,565 issued November 25, 1919. v

The object of the invention is to provide simple and eliicient means .for moving the stack laterally and longitudinallyT relatively to the locomotive track and also vertically.

Another object is toprovde a stack'ofmovable with the truck to protect the apparatus against rain, snow and the like.

l/Vith these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described, and their specifically pointed out in the claims,` and inthe drawings illustrativeof the preferred embodiment of tion. f

In the accompanying drawingr Figure 1 represents a side elevation of the the invenapparatus constituting this invention shown applied to the roofvof a locomotivev s hed, the parts being broken away and in section. l

conduct the smoke issuing therefrom to the louter atmosphere.

This stack 10 is composed of telescopiiig sections 14 and 14, the upper section 14: being fixed and the llower sectioiillln movable vertically by means hereiiiafter to be described. Y

Truck supporting tracks 7 are carried by hangers 8 .depending into the shed from'the roof 5, said tracks being arranged above and parallel with the locomotive track rails and below therslot in the roof, the latter being of a length substantially the same as the track 7, to provide for the movement of the truck tc be described the-full length of said track. Y

A stack carrying truck 9 is equipped with double flanged wheels 10a mounted to travel on the track rails 7, the double flanges of Ithe wheels preventing spreading of the rails or lateral displacement of the truck.

The truck 9 may be of any desired construction aiid carries in addition to the stack 10 a cover plate 15 to prevent the entrance of rain and snow through the slot lin the roof.

A plate 17 is mounted to move trans- -versely of plate 15 in guides 1S carried by plate l5 and said plate 17 surrounds the stack 10 and is secured thereto to provide for the lateral movement of the stack relatively to the locomotive track.

The truck 9 carries at its opposite ends is of a length to permit it to hang within j convenient reach of the operator so that when the wheel 22 is rotated in one direction or the other the desired longitudinal movement of the track 9 will be accomplislied. Y

A suitably supported platform or truck 25 through which the stationary stack portion or section 14.- projects is mounted to travel on transverse track i'ails 12 of the frame structure of the main truck 9 to provide for ythe lat-eral movement of the stack relatively tothe locomotive track rails.

An angular depending bracket arm or plate 27 is hingedly mounted at 27a on a Vpintle 27b carried by the platform 25 and this plate pivotally supports at its lower end a rock shaft 28 carrying spaced parallel crank arms 29 connected by relatively short links 30 with diametrically opposed trunnions 31y secured to the vertically movable stack section 14a.

A link 29a is connected with each of the' i 29 with link 29a is composed of two cast iron or steel disks 52 and 53 between which is -disposed a wooden fiber disk 54 all of which are connected by a bolt -55 passing centrally therethrough and through arm 29 and link 29 as is shown clearly in Fig. 4. A coil spring 56 is mounted on the bolt 55 between its head and the link 2 9, the other end of the bolt outside arm 29 being equipped with jam'nuts soV that the disks are held in frictional engagement for a purpose presentlyY to be described, the tension of the spring 56.

being adjustable to vary the engagement of the disks. Y

Each ofthe metal disks 52 and 53 is pro- 'vided onits outer face with spaced laterally projecting ribs 57 between which the arm 29 and the link 29a are designed to be disposed. v

The bracket or vplate 27 being hinged at its toppermits it to swing back and forth so that all possibility of jamming of section 14n of the stack is prevented, the movement of said stack section being perpendicular owing to this peculiar connection.

The shaft 28 has secured to its opposite ends, arms 32 and 32 which carry at their terminals counterbalancing Weights 33 and 33 which assist the arms 29 in the operation ofV actuating the vertically movable smoke stack section 14a. A lever 34 is fixed midway its ends to one end of shaft 28 and is equipped with cables as 35 positioned convenient to the operator.

From the above description it will be obvious that the friction clutch provided between links 29' and arms 29 Vwill operate to hold the adjustable section 14"L of the Smoke stack at anyv desired adjusted position andv will be easily releasable by a pull exerted on a cable 35 secured to each end of the lever 34. The lower end Vofthe vertically movable stack section 14a is flared as shown at 41 for convenience in positioning it over a locomotive stack and a section 42 of said lower end is cut out and hinged to adapt it to be tilted out of normal position by the lateral withdrawal of the locomotive smoke stack from the stack 10 without injuring either.

Parallel laterally extending arms 36 are pivotally secured at one end to brackets 37 on the frame of truck 25. The outer ends of thesearms 36 are pivoted' to the lower ends of depending crank arms 38 carriedby a l rock shaft 39, journaledV in bearings 40 of a U-shaped bracket 43 fixed to the 'frame of truck 9. A lever 44 is fixed midway its ends to shaft 39 the ends of which are conven-a iently laccessible and oscillating the "sh'aft`39 to laterally adjust truck 25 and the smoke stack l0 carried thereby. Y

The rods 45 connect the side members of truck 9, as shown in'Fig. 2, to strengthen' the structure. f
